Answer 1

Step-by-step explanation:

Lets solve This problem

Q.quite Easy

Solution:

Let the marks in his 1st test be x

Marks in 2nd rest=x+10

As given in question 5 times the score of second test=square of 1st

5(x + 10) = {x}^{2}5(x+10)=x2

{x}^{2} - 5x - 50 = 0x2−5x−50=0

{x}^{2} - 10x + 5x - 50x2−10x+5x−50

\begin{lgathered}x(x - 10 ) + 5( x - 10) \\( x + 5)(x - 10) \\ x - 10 = 0 \\ x = 10\end{lgathered}x(x−10)+5(x−10)(x+5)(x−10)x−10=0x=10

Answer=10 marks
